Lock and Key Service in Walnut

How this works in Walnut

A lock and key service does four things, and most visits mix several of them. First, keys: copying a working key, or better, cutting a fresh one to the lock's original code so it's sharper than the worn key in your pocket. Second, rekeying: changing the pins inside a cylinder so old keys stop working and a new key takes over, without replacing the lock. Third, repair: freeing a sticky cylinder, tightening a loose deadbolt, adjusting a strike so the bolt throws without a shove, or fixing a latch that won't catch. Fourth, replacement: installing new deadbolts, knobs, levers, mortise locks or smart locks when the old hardware is truly done. Around those four sit the small locks: mailbox, cabinet, padlock, gate and drawer locks. Our van carries key machines, the common blanks for Kwikset, Schlage, Weiser, Yale and commercial keyways, pinning kits, and a stock of locks, so most of this happens on the spot in Walnut. Some restricted keys and specialty hardware have to be ordered, and a few car keys are dealer-only. We'll tell you which on the phone.

What we can do on-site

• Rekeying to a new key. Rekeying swaps the pins inside a cylinder so the old keys stop working and a new key takes over. The lock itself stays on the door. For a house in Walnut with sound hardware, it's the quickest, least wasteful way to reset who has access after a move, a lost key or a roommate leaving.
• Keying every door alike. Keyed-alike setups make life simpler for families, caregivers and dog walkers. Everyone carries one key, and a lost key means one rekey, not five. We stamp or color-code the new keys if you like, so nobody confuses the house key with the car or mailbox key on a crowded ring.
• Repairing sticky, loose and binding locks. A deadbolt that only throws when you lean on the door is usually an alignment problem. Doors sag and frames shift, so the bolt rubs the strike. We adjust or relocate the strike plate, tighten hinges and confirm the bolt extends fully without force, which is also what makes it secure.
• Replacing worn-out locks and deadbolts. Smart locks, keypads and mortise locks are replacements too. We can install a Schlage Encode, Yale Assure or Kwikset Halo, or a matching keypad deadbolt, and key its backup cylinder to the rest of your house. One mechanical key still works everywhere, even if a battery dies.
• Restricted and high-security keys. If your business or home already uses a high-security system, bring the key card or authorization paperwork. Without it, the system is designed to stop anyone, us included, from making copies. That's the point of the system, and we'll respect it.

How Walnut shapes the job

Residents of 55-plus communities in Walnut often want hardware that's easier on the hands. We swap round knobs for lever handles, cut keys with large easy-grip heads, and key every door alike so there's only one key to manage. A keypad deadbolt can eliminate fumbling with keys entirely, and we'll make sure a trusted family member has a working spare.

Commuters in Walnut leave early and get home late, so lock and key errands rarely fit into the day. That's where a mobile visit helps. We start at 6:30 a.m. every day and work until 11:30 p.m., so a rekey, new copies or a spare car key can happen before you leave or after you're back, with your car sitting in the driveway.

Horse properties in Walnut need keys for tack rooms, feed rooms, barn doors, trailer doors and hitch locks. Most of these live outdoors in dust and heat. We supply shrouded padlocks that resist cutting, rekey compatible locks to a common key, replace corroded latches, and lubricate everything with a dry product that won't attract hay dust or grit. A labeled key board in the barn keeps the right key with the right door.

Example situations

• Imagine a property on the edge of Walnut with a barn, a well house, two sheds and a pump enclosure, each closed with a different padlock and a ring of mystery keys. We'd open the padlocks nobody can match, replace them with weather-resistant padlocks keyed alike, and give the owner one key for every outbuilding plus clearly labeled spares.
• Imagine an accounting office that discovers the night before an audit that nobody has keys to three locked file cabinets. We'd read the code stamped on each cylinder face, cut keys on site, and test them in every drawer. If one lock has been forced in the past, we'd replace it and key it to match the others.
• Say two households merge into one home in Walnut, and the combined key ring now includes keys for locks nobody can identify. We'd sort which keys go where, rekey the exterior locks to one key, and swap the one mismatched deadbolt for a compatible model. The old keys go in a bag marked retired, and everyone carries a single house key.
• Picture a family with a new teen driver who needs a house key and a spare for the car. We'd cut a house key to code so it turns cleanly, program a spare transponder key for the sedan in the driveway after checking the registration, and suggest a keypad deadbolt so nobody's locked out when a key gets left at practice.

How the visit works

1. Send us your whole list. The more you mention on the first call, the fewer trips it takes. We'll ask how many doors, what kind of locks, and whether any keys are missing completely. Then we can plan one visit to Walnut instead of three, and bring blanks for every keyway we expect to see.
2. Brands, codes and photos. If you have original key tags, paperwork from a lock purchase or a car key code card, set them aside. A code lets us cut fresh keys to the factory specification rather than copying the wear on an old key, and it sometimes saves taking a cylinder apart.
3. One quote for the visit. We quote the whole list together: each task, any parts and the drive from San Bernardino. You'll know the total before we come out, and if something on site turns out different from what you described, we explain and requote before touching it.
4. Arrival, ID and a walk-through. Our technician carries photo ID, and our license is posted in the van. Once we've confirmed what you want done and who should end up holding keys, we start with the item that matters most to you, usually the door you use every day.
5. Cutting, pinning and repairs on site. If we hit a surprise, like a seized cylinder or a lock that won't take new pins, we stop and talk it over. You decide whether to repair, replace or leave that item, and the quote updates only with your approval.
6. Every key tested in every lock. We hand over the keys counted and labeled if you'd like, and an itemized invoice listing each task and part with our license number, LCO7891. Old keys that no longer work can go back to you or into our disposal bag.

Pricing factors

• How many tasks are on the list. Adding something on site is fine, and we'll price it before doing it. Still, the most efficient visits are the ones we planned for, because we bring the right blanks, cylinders and lock parts instead of discovering we need a second trip.
• Rekey, repair or replace. Replacing a lock to change the key is a common overspend. If the lock works well and you like how it looks, rekeying gets the same security result. We'll tell you plainly when replacement is worth it and when it isn't.
• Key types and blanks. How many copies you want matters too. The first key on a new combination includes the setup; extra copies cut at the same time cost less each than coming back later. Decide on the number for your Walnut household, including spares for neighbors or caregivers, before we arrive.

What not to do

• Spraying household oil or penetrating spray into a lock. It loosens things briefly, then turns into a sticky paste that collects dust and grit. Locks need a dry lubricant made for them, and a gummed-up cylinder may need cleaning before it works properly again.
• Ignoring a wobbly deadbolt or loose knob. Loose hardware only gets worse, and a lock that shifts in the door is easier to force. A few minutes of tightening, or a replacement spindle or screw, prevents a failure at a bad moment, like when you're rushing out.
• Trusting a Do Not Duplicate stamp to protect a key. Plenty of places will copy it anyway because the blank is common. If you truly need to control copies, the answer is a restricted keyway that requires authorization and controlled blanks.

Advice before you book

• On cluster mailboxes, check who's responsible before replacing a lock. The individual compartment lock is often the property owner's or HOA's responsibility, while the post office controls the parcel lockers. If you rent, your manager may already keep spare keys. Have ID showing your address ready when we come to replace yours.
• Write down the key number stamped on new padlocks and file cabinet locks, and store it with your home records or in a note on your phone. With that number, a replacement key can often be cut by code without opening, drilling or replacing the lock.
• Look at the face of your lock before you call. The brand name is stamped around the keyhole or on the deadbolt's thumb turn side. Knowing whether it's Kwikset, Schlage, Weiser or another brand tells us which blanks and pins to bring to Walnut. If the face is worn smooth, check the key bow instead.
• Lubricate locks with a dry lubricant made for them, such as a PTFE spray or powdered graphite. One short puff in the keyway, then work the key in and out a few times. Heavy oils feel good for a week and then trap dust. If a lock stays stiff after that, the pins likely need service.

About Walnut: Mt. San Antonio College opened in 1946 on what is now a campus of about 420 acres and enrolled nearly 30,000 students in fall 2024.

Here are our real hours: 6:30 a.m. to 11:30 p.m., every day of the week, weekends included. We aren't a 24/7 locksmith and won't pretend to be. If you're locked out while we're closed, your auto club or your property manager's emergency line may get you in sooner, and we're glad to book you for the moment we reopen.

We won't open a door for someone who can't show they live or work there, however convincing the story. That includes a person who has moved out, a former partner, or anyone caught up in an eviction dispute. The rule protects you the same way it protects every other household we serve: no proof, no entry.
